Typically, what percentage of the blood is made up of plasma?

Typically, plasma makes up about 55% of total blood volume in the human body. Blood consists of several components, and plasma is the liquid portion that carries cells, nutrients, hormones, and waste products throughout the body.

This percentage can vary slightly depending on factors such as hydration levels and individual health conditions. In a healthy adult, blood is composed of about 40-45% red blood cells (erythrocytes), 1% white blood cells (leukocytes) and platelets (thrombocytes), and the remaining 55% is plasma.

Plasma itself is composed of approximately 90% water, with the rest consisting of proteins (such as albumin, immunoglobulins, and fibrinogen), electrolytes, nutrients, hormones, and waste products. This balance is crucial for maintaining blood pressure, regulating body temperature, and providing essential substances for cellular functions.
